SHURflo Operating Instructions, Performance,
Specifications and Parts Manual
Description
SHURflo bronze, pedestal, self-priming, positive-displacement, flexible impeller pumps provide a nearly pulseless flow with no
metal-to-metal contact. This pedestal pump drive series includes a 303 stainless steel drive shaft with heavy-duty ball bearing
and carbon graphite bushing, providing for direct drive or pulley operation. Features include: bronze and/or brass pump
body, cam and cover; standard Buna-N mechanical seal with carbon ceramic faces and Nitrile impeller.
Uses: Handle a wide range of industrial, marine, agricultural and commercial applications where non-abrasive fluids
compatible with pump wet-end construction component materials are pumped. Pumps are suitable for the transfer of
non-lubricating fluids, mild abrasives, fluids containing small particles in suspension, and a wide variety of viscous fluids such
as petroleum-based oils, silicone greases, and hydraulic fluids. These units are ideal for water drainage transfer, barrel
emptying, machine coolant recycling, and an assortment of related utility activities.
NOTE:
Flexible impeller failure will occur immediately if pump is run dry, and this is not covered under warranty. Use caution
to not touch the pump if you have dry run it, because it will be extremely hot.
• Flows up to 36.5 GPM at 3450 RPM.
• Maximum discharge pressure is 25 PSI (60 ft. of head).
• Max. RPM: 3450.
• Suction lift to 13.5 ft.
• Buna-N mechanical seal with carbon ceramic wear faces and 18-8 stainless steel components.
• Maximum viscosity up to 500 SSU and 25 PSI (60 ft. of head) at 1725 RPM or run at reduced speeds to handle a wide range
of pump fluid viscosities (up to 2500 SSU) and specific gravity (up to 1.3). DO NOT pump oils or petroleum derivatives with
optional neoprene impellers. (Maximum torque loads are found in the performance chart.)
• Pumps can operate bi-directionally (reversible).
• Temperature range with Nitrile impellers is 0°F - 180°F (optional neoprene impellers is 15°F - 130°F).
• Includes a 303 stainless steel drive shaft with heavy-duty ball bearing and carbon graphite bushing, providing for direct
drive or pulley operation.
BRONZE MODELS –
Excellent for water-based fluids. Features include: bronze and/or brass pump body, cam and cover; standard
Buna-N mechanical seal with carbon ceramic faces and Nitrile impeller. Wet-end parts are constructed from bronze, brass, Nitrile,
carbon, ceramic and stainless steel (18-8, 303 and/or other 300 series).
REPAIR IMPELLERS AND OPTIONS –
Standard impellers are Nitrile, and they and the optional neoprene impeller can be
located in the repair parts list pages in this manual.
NOTE:
Bronze and 316 stainless steel flexible impeller pumps are also available as close-coupled models for custom installation. They are
equipped with motors.
WARNING: Do not use to pump flammable or explosive fluids such as gasoline, fuel oil, kerosene, etc. Do not use in flammable
and/or explosive atmospheres. When pumping hazardous or dangerous materials, use only in a room or area designated for that
purpose. For your protection, always wear proper clothing, eye protection, etc. in case of any malfunction. For proper handling techniques
and cautions, contact your chemical supplier, insurance company and local agencies (fire dept., etc.). Failure to comply with this warning
could result in personal injury and/or property damage.
